Application meu August 24., 1925.

This invention relates to antifriction bearings and is herein shown, by way of example, as embodied in a unit handling roller bearing assembly. l

An object of the linvention is to provide an improved roller bearing composed of a small number of. parts that are easily assembled and disassembled. Another object is to provide an inexpensive roller bearing in which 10 the rollers are retained in an outer race as a unit, the retaining means eliminating riveted joints and such undesirable features.

. To these ends and alsoto improve generally upon devices of the character indicated 15 the invention consists in the various matters hereinafter described and claimed.

In the drawings, Figure 1 is an end view. Figure 2 is a transverse central section.

Figure 3 is a plan view of the outer race 20 blank before it is bent to form a split sleeve.

Figure'4 1s a detail view of one of the end rings. The numeral indicates an outer raceway formed of a planished steel blank bent to having a sh-tail joint 12. The sleeve has a (plurality of pairs of slots 14 and is arrange to wrap, around a pair of end rings 16 which have lugs 18 to enter the slots formaking'an interlocking connection.

than the lugs so that the lugs will properly enter them in the wrapping process. The split sleeve is arranged 'to sl1p into any sort of c lindrical `outer housing not shown whic holds it compressed onto t e end rings. Oil openings 20, for cooperation with an oil channel in the housing, may be punched in the sleeve.- The sleeve encircles a circular series of cylindrical rollers 22 which may be solid orof the hollow,`wound` type sho/wn and the end rings abut the flat ends of the l rollers and prevent them from moving longitudinally in the sleeve.

There is provision for holding the rollers outwardly in the sleeve to make a unit handling bearing assembly when the shaft 24 or other'inner race` is not in place, as durin shipment. Thiscom rises a retaining ban 4 26' having' -rectangu ar roller spacing and guiding openings 28. The band26 is arranged in a circle smaller than' the circle through the centers of the rollersso'that the rollers are held against inward escape and are guided by the front and rear edges of the ited to Serial No.' 51,920.

openings. The -band 26 may be formed by punching a sleeve, or as shown, by punching the openings in a ilat blank and turning the blank into a ring and vwelding the ends as at 30. The band is of smaller diameter than the end rings 16 and extends within andpast them, a little clearance being left at 32 to allow the' retainer to float on the rollers. By bending outwardly the ends of the split sleeve, any of the par-tsl of the bearingis readily removable for any purpose.

Although the invention has been 'described by reference to an illustrated embodiment, it should be understood that, in its broader aspects, the invention is not necessarily limthe specific construction selected for mere' illustrative purposes. y

I claim: 1.` In a bearing, forming an- 'outer raceway, of rollers within the sleeve, rings arranged within to abut the ends of the rollers, sleeve having interlocking means to allow a liendable split sleeve a circular series andapair. of
